The cluster of spray-painted stenciled messages - “Keep New England White,” “Death to Israel,” and “Defend New England” - are the work of the Nationalist Social Club, which took credit on Telegram, a social media platform frequented by white supremacist and other hate groups. Lopez says the messages were spray painted on a popular mural along a bike trail in the city’s Ward 4, an economically and culturally diverse neighborhood. A recruitment message was also graffitied on a nearby dumpster, and stickers bearing the group’s name have also popped up around Nashua.
